` `5 Claims.

its carrier by rule-of-thumb and then to try by actual seaming ci a can-end to acari-body "whether or not the .teaming-roller occupies the correct seaming position. This operation is usually repeated a number of times before the -desired adjustment is obtained and, as there are usually a number of .teaming-rollers ina machine, a considerable amount ofy time is expended in obtaining correct position of the parts.

The main object of this inventionV is to obviby providing means whereby the correct seaming position of the seaming-rollercan be accurately and quickly determined without the necessity of resorting to repeated test seaming operations.

The invention consists essentially in providing Acomplementary gaging means that .include abutment surfaces on the seeming-roller and chuck which when brought together by adjustment of the scanning-roller on its carrier determinethe correct seaming position of the seaming-roller- Other features will appear as the ,specification proceeds.

In the accompanying drawings the invention is disclosed in a concrete and preferred form in which l Fig'. 1 is a vertical sectional view substantially on the plane of irregular line I-I of Fig. 2;

Fig. 11.is u fragmentary sectional view of the ate the necessity ior this trial-,and-error method plane of line 9 9 of Fig. 12 showing the secondabutment member of the second-operation seaming-tool and the central chuck; and

Fig. Y12 is a diagrammatic plan view of the seeming-tools and seamer-cams showing both the iirst and second-operation seaming-tools in their outer position.

Referring to Figs. l0 and 11, reference character IE5 indicates a can-body and I6 is the canend. Il is the central chuck of the machine that engages the can-end, I8 is the first-operation steaming-roller and I9 the second-operation seeming-roller. The gaging means consist of an abutment surface 2li on chuck I1 and complementary abutment surfaces 2| on the firstoperation seamlng-roller and 21a. on the secondoperation seaming-roller. The parts are so arranged that when the complementary abutment surfaces on the chuck and the scanning-rollers are brought together, said steaming-rollers occupy the correct seaming position..

The general principle of the invention now being understood, a more detailed `description will be given.

Central chuck II engages iny connection with the usual pedestal shown) clamps -the work .during the seamingoperation. 22 is'the seamer-head and, in accordance with usual practice, the seamer-head and the work and chuck are given a relative the can-end and rotative movementby one of the'many eXpedii' ents Well-known inthe art. In the present nstance, the work and chuck stand still and the seamer-head rotates. 23 and 24 indicate the first-operation and. second-operation seamercams and, in accordance with well-known practice, there is a diierence of one revolution per cycle of the seamer-head and seamer-cams. In the .present instance, four seaming-rollers are employed: two r'st-operation rollers Il and two second-operation rollers I9 all carried by theA seamer-head. As all the seaming-roller mountings. are alike, except for differences to be pointed `out later, itfwill only be necessary to describe one of said mountings. Taking as an example first-operation seaming-roller I8, it will be seen" that said seaming-roller is mounted on a carrier 25 and that suitable means are provided to impart to this carrier a movement of a given amplitude with respect to the chuck. .The actuating means consist of cam 23 and suitable con nection. In the present instance a detailed 'description of the parts is as follows: 26 is apivot memberrotatably seated in the seam'er-head and supporting at one end carrier 25 and' having at its other .end anA arm 2l provided with a cam- (not roll 28 which latter engages seamer-cam 23. It will be apparent that, when cam-roll 28 reaches the high point or surface of seamer-cam 23, seamer-roller I8 will move toward the Work and chuck. Centrifugal force acts to throw the seaming-roller outwardly when the high point or surface of the seamer-cam passes the point where cam-roll 28 is located. Suitable means are provided to adjust seamer-roller I8 with respect to carrier 25, such means, in the present instance, taking the form of eccentric 29 which can be turned in its seat 3D on carrier 25, as by means of pin SI. The end of carrier 25 is bifurcated as indicated at 32 and a bolt or screw 33 is provided to cause the bifurcated end of the carrier to clamp the eccentric in its adjusted position.

The method of predetermining the correct position of the seamer-roller with respect to the work to be acted upon is as follows: cam-roll 28 is brought against the high surface of seamercam 23 thereby causing seamer-roller I8 to move toward the chuck. Said seamer-roller I8 is now adjusted on carrier 25 by means of eccentric member 29 thereby bringing abutment surface 2l in contact with abutment surface 20 on the chuck, and it will be noted that this adjustment is accomplished without changing the amplitude of the movement imparted by cam 23 to the seaming roller. Preferably the adjustment of eccentric member 29 is continued slightly after abutment surfaces 2| and 2D engage, this action being permitted by the yieldable connection formed by pivot member 26 which is provided with two longitudinal slots or grooves 34. In other words, a slight torsional twist is imparted to pivot member 26. Screw 33 is now tightened to hold eccentric member 29 in its adjusted position, Surfaces 2l and 2G are accurately iinished surfaces, and it will now be found that the proper seaming position of seamer-roller IB has been predetermined and established. It will thus be seen that, during the seaming operation, i. e. while cam 23 is engaging cam-roll 28, circular abutment surface 2l will travel in contact with circular abutment surface 2U and will thus maintain a proper relationship between seamer-roll I8 and the work.

It is unnecessary tc repeat the description of the mounting for second-operation seaming-roller I9 except to say that numerals 25 to 34 inclusive with the exponent a, refer to the corresponding elements of rst-operation seaming-roller I 8. The only difference in the two seaming-roller assemblies resides in the mounting of cam-roll 28a which has an eccentric member 35 whereby the cam-roll can be adjusted into and out of contact with the high point of seamer-cam 2d.

In Fig. 12 is a diagrammatic showing of the relationship between the seamer-cams, the camrolls, the seaming-rollers, the chuck and the work. 'I'he principal object of this diagram is to show that, at one point in the seaming-cycle, both the first and the second-operation seamingrollers are out of contact with the work so as to allow the latter to be introduced into, and withdrawn from, the plane of the seaming-rollers.
